refactor: consolidate duplicated UI score/color/badge logic into lib/

- Add matchScoreHex(), criterionScoreColor(), criterionScoreTextColor() to lib/utils.ts
- Add RESULT_TYPE_META (labels + colors) to lib/ds.ts as single source of truth
- Remove 5 local scoreColor() functions: StrongMatchMiniCard, MatchListCard,
  pipelineUtils (re-exported as matchScoreHex), CriterionRow, ScoreBreakdownPanel,
  ScoreInlineBreakdown
- Remove local RESULT_TYPE_META/TYPE_META from MatchCardHeader, ResultTypeBadge;
  remove RESULT_TYPE_LABEL/COLOR from pipelineConstants — all now use lib/ds.ts
- Replace local confidenceColor() in MatchCardHeader, ConfidenceFieldBadge,
  ReliabilityScorePanel with confidenceHex() from lib/utils.ts
- Replace local qualityColor() in propertyHelpers, DataQualityWidget with
  dataQualityColor() from lib/utils.ts
- Fix FUTURE_AVAILABILITY label inconsistency ('Future'/'Zukunft' → 'Zukunftssignal')
- Fix EXTERNAL_MARKET label inconsistency ('Direktinserat' → 'Plattform')
- tsc --noEmit passes with zero errors
